REPAIR-SPINDLE FOR COCKS.

SPECIFICATION forming part of Letters Patent No. 728,699, dated May 19,1903.

Application filed November 26, 1901. Serial No. 83,763. (No model.)

To all whom it may concern:

Be it known that LEDWARD J. GALLAGHER, a citizen of the United States,residing at Philadelphia, county of Philadelphia, State of Pennsylvania,have invented certain new and useful Improvements in Repair-Spindles forCocks, of which the following is a specification.

My invention relatesto cocks and faucets,

such as bib-cocks, and more particularly to means for repairing the saidcocks without necessitating the-entire renewal. of the cock.

In cocks and faucets of that character in which a screw-threaded stem orspindle is employed for giving the valve a reciprocating movement-foropening and closing the spindle is usually screw-threaded to engage withscrew-threads on the inside of the body of the cook or with apermanently-fixed sleeve therein, and in the constant use of the samethe screw-threads on both the spindle and the body of the cock become intime so worn that it is no longer possible to maintain a fluid-tightjoint between the valve-seat and the valve or between the stem and thebody. Prior to my invention when this condition occurred it has alwaysbeen necessary to remove the entire cock and replace it by a new one,which operation required the services of a skilled plumber, and in suchoperation the most difficult and tedious part is the formation of thewipe-joint between the body of the cock and service-pipe, which in mostcases is of lead.

My object is to dispense with the necessity of removing the cock fromits service-pipe, thereby avoiding the necessity of making thewipe-joint by providing a repair-spindle for such cocks which can beeasily substituted for the worn-out spindle by any unskilled person at alow cost and in a very short time and by means of which the necessaryrepair can be efiected at a much less cost than heretofore.

With this object in view my invention consists in a repair-spindlecarried by a threaded sleeve adapted to be inserted inside of thescrew-th readed body of the cock, with means on the sleeve for holdingand locking the same in place on the body of the cock, such meansextending in a radial direction sufficiently beyond the exterior of thesleeve to admit of support upon screw-threaded bodies of cocks ofvarious sizes, as hereinafter claimed.

In the drawings, Figure 1 is a vertical sectional view of a cock,showing the worn-out thread on spindle and body. Fig. 2 is a similarview showing my repair-spindle substituted for the worn-out spindle, andFig. 3 is a perspective view of the parts of-n1y spindle ready forassembling.

' Referring now to the drawings, in which the same reference charactersrelate to the same parts in all the views, thenumeral l indicates thebody of a bib-cock, the inlet-pipe 2 of which is adapted to be joined tothe servicepipe and the discharge-nozzle 3 of which is adapted, asusual, to discharge the fluid or liquid downwardly. In the partition4=is the usual valve-seat 5, against which the valvehead 6, carried bythe spindle 7, seats to cut off the flowof liquid. This valve-head 6 isformed on the spindle, in the lower end of which is the usualscrew-threaded hole for the reception of the screw 8, the head of whichholds the washer 9 against the valve-head.

The spindle 7 has screw-threads 10on an enlargement just above thevalve, which screw-threads engage with the screw-threads 11 on theinside of the body of the cock, whereby the spindle may be raised andlowered by turning the handle 12 thereof in the usual way.

A flanged cap 13 screws down upon the top of the body of the cock and isprovided with the usual washers or packing to make a tight joint.

In time the constant raising and lowering of the valve through themedium of its spindle causes the screw-threads 10 and 11 to be come soworn as to be useless for the purpose intended, as indicated at a and b,Fig. l, and further renewals of the Washer 9 become inefiective, so thatit is necessary to renewthe entire cock unless a means-be provided whichwill avoid this necessity. I provide such .means by the constructionshown in Figs. 2

and 3, wherein 7 is a new spindle,having at its lower end the valve-head6 to which the washer 9 is secured by the usual screw. Mounted upon thisspindle 7 is a sleeve 13, provided with screw-threads 14, engagingthreads 15 on the spindle 7. The diameter of the sleeve is suflicientlyless than the screwthreaded portion of the body of the cock so as topermit the said sleeve to slide freely within the same. At thetop ofsaid sleeve is a plurality of laterally-projecting lugs 17, which areadapted to be seated in corresponding notches 16, that are cut in thetop of the old body 1 of the cock. These lugs confine the sleeve to thebody of the cock and prevent the said sleeve from turning therein.

The old cap 13, handle 12, body 1, and screws may be used, so that inrepairing a cock all that is requisite for the purpose is the filing ofnotches 16 in the body of the cock after the removal of the old spindleand valve, and with the parts assembled in the order indicated in Fig.3, the sleeve being at the lower end of the spindle, resting on thevalve-head 6, thespindle and sleeve are simplyinserted in the body untilthe washer rests on its valve-seat, the lugs 17 dropping into thenotches 16. Then the cap 13 is screwed home, thereby confining thesleeve against longitudinal movement, so that the movement of thespindle operates the valve, as in the old structure.

The operation of repairing a worn-out cock is thus rendered very simpleand inexpensive as compared to the prior practice, which ne- I claim asmy invention- 1. As a new article of manufacture, the herein-describedrepair-spindle for bib-cocks consisting of a spindle havingscrew-threads thereon, a screw-threaded sleeve mounted on said spindleand of a diameter sufficiently less than the internal diameter of thescrewthreaded body of the cock to be repaired to permit it to slidefreely within the screwthreaded body of said cock, said sleeve havingsupporting means extending sufficiently far in a radial direction fromthe exterior of the sleeve to admit of support upon screwthreaded bodiesof cocks of various sizes, substantially as described.

2. As a new article of manufacture, the herein-described repair-spindlefor cocks havingscrew-threaded bodies consisting of aninternally-screw-threaded sleeve of a diameter sufficiently less thanthe internal diameter of the screw-threaded body of the cock to berepaired to permit the said sleeve to slide freely within thescrew-threaded body of said cock and having an integral extension orextensions at its top projecting radially beyond the exterior of thesleeve a sufficient distance to overlap and engage the screw-threadedbodies of cocks of various sizes, whereby the sleeve may be clamped tothe same, and a spindle having screw-threaded engagement with saidsleeve, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
